xfs: kill the XFS_WANT_CORRUPT_* macros

The XFS_WANT_CORRUPT_* macros conceal subtle side effects such as the
creation of local variables and redirections of the code flow.  This is
pretty ugly, so replace them with explicit XFS_IS_CORRUPT tests that
remove both of those ugly points.  The change was performed with the
following coccinelle script:
